Presonus Eris 3.5 for Beginners: A Complete Guide
First-time setup of studio monitors involves decisions about placement, connection and listening habits that are not obvious. This guide covers each step for new users.
Setting up studio monitors for the first time introduces a set of decisions about placement, connection and listening technique that are not immediately obvious. If you have a pair of these monitors and are starting from scratch, this guide covers what to do in what order and how to build a useful reference listening environment.
Physical Placement
Place both monitors at ear height when seated at your listening position. The ideal configuration forms an equilateral triangle: each monitor the same distance from your ears and from each other, angled inward to point at your head. A distance of approximately 80–100 cm from ear to each speaker works well for desktop use. Keep the rear of the cabinet at least 15–20 cm from any wall — the rear port vents bass, and positioning too close to a wall causes bass buildup that distorts the low-frequency balance. Desk isolation pads or small foam wedges under the monitors prevent vibration transmission through the desk surface.
Connecting to Your Audio Interface
The most reliable connection is via balanced TRS cables from your audio interface's line outputs to the monitor's TRS inputs. Set the monitor's rear gain control to a moderate position and use your interface's output level control for volume adjustment — this maintains a consistent gain structure. If you are connecting from a laptop or computer without a dedicated interface, the unbalanced RCA inputs accept that signal, but an audio interface will give substantially better results and is recommended for any serious recording or mixing work.
Calibrating Listening Level
Choose a fixed reference listening level — typically a comfortable volume at which you can mix for an hour without fatigue. Set this by playing a known reference track at a level that feels moderate, then do not change it during a mixing session. Consistent level is important because the ear's frequency response changes with volume; decisions made at one level may not translate to another. Many engineers use an SPL meter to calibrate to 79 dB SPL at the listening position, then make level changes only intentionally.
Understanding the Bass Limitation
The 80 Hz low-frequency rolloff means you will not hear reliable information below this frequency from the monitors. This is normal and manageable. The practical approach is to check your mixes on headphones for sub-bass content (anything below 80 Hz) before finalising. Good closed-back headphones reveal low-frequency content that the monitors cannot reproduce. Using both reference sources together gives a more complete picture of what the mix actually contains.
Building Your Ear
The most valuable thing you can do in the first weeks is listen critically to commercial recordings you know well. Play a reference track, close your eyes and focus on specific elements — the balance between bass and kick, the level of a lead vocal in the mix, the high-frequency detail on cymbals. The PreSonus Eris 3.5 delivers enough accuracy to begin this process of training your ears to identify mix characteristics. Over time, you will develop an understanding of how what you hear on these monitors translates to other playback systems. See the mistakes guide for common errors to avoid in the early stage.
